DETAILED DESCRIPTION

To facilitate understanding of the present disclosure, some concepts involved in the embodiments of the present disclosure are briefly introduced here.

1. An example of NTN (non-terrestrial networks) communication method is shown in Figure 1.

According to the different ways in which satellites process signals, they can be divided into transparent transmission mode and regeneration mode. The transparent transmission mode is shown in Figure 2. The station sends the base station signal to the satellite, the satellite converts the signal to the satellite frequency band and then sends it to the terminal (also called terminal equipment) through the satellite frequency band. In addition to frequency conversion and signal amplification, the satellite does not demodulate the base station signal.

The regeneration mode is shown in Figure 3. After the NTN ground station sends the base station signal to the satellite, the satellite first demodulates and decodes the signal, then re-encodes and modulates it, and sends the regenerated signal through the satellite frequency band.

Table 1 below gives the satellite altitude, orbit, and satellite coverage of a typical NTN network:

Table 1

It is understood that each element in Table 1 exists independently. These elements are exemplarily listed in the same table, but it does not mean that all elements in the table must exist at the same time as shown in the table. The value of each element is independent of the value of any other element in Table 1. Therefore, those skilled in the art can understand that the value of each element in Table 1 is an independent embodiment.

2. Discontinuous reception (DRX): For IoT services with infrequent data transmission, data transmission is usually bursty. When there is no data transmission, the receiving circuit of the terminal device can be turned off to reduce power consumption, thereby increasing battery life. In each DRX cycle, the terminal device will detect whether there is a downlink service arrival. Among them, a DRX cycle is equal to the sum of the terminal device wake-up time and the terminal device sleep time. The terminal device wake-up time is the time when the terminal device monitors the paging channel. During this time, the terminal device is in an awake state; the terminal device sleep time is the time when the terminal device enters sleep mode and does not monitor the paging channel in order to save power. During this time, the terminal device is in a sleep state. Due to the short DRX cycle, for example: the cycle can be 1.28s, 2.56s, 5.12s or 10.24s, it can be considered that the downlink service is reachable at any time. Therefore, DRX is suitable for services with high requirements for latency, but the power consumption is relatively high.

3. Extended discontinuous reception (eDRX)

Depending on the number of deployed satellites, when the number of satellites is small, the satellite coverage may be discontinuous, which means that the terminal device may be within the satellite coverage at one time and outside the satellite coverage at another time.

If the terminal device wants to maximize its power consumption, it can request eDRX to the mobility management entity (MME) through a nonaccess stratum (NAS) message (registration or tracking area update (TAU) procedure). The NAS message includes its preferred eDRX cycle. If accepted, the MME will configure eDRX for the terminal device, transparent to the access network equipment. The eDRX configuration includes the eDRX cycle (TeDRX) and the PTW (paging time window) length. When the MME sends the paging of the terminal device to the access network device, the eDRX configuration will be provided together. The eDRX cycle length configured for the core network (CN) equipment is 5.12s, 10.24s, ..., 10485.76s (that is, 1024 Hyper system Frame Numbers (Hyper SFNs)). The radio access network (RAN) only supports a maximum of 1024 Hyper SFNs because the Hyper SFN broadcast in the system message is only 10 bits).

PTW is not applicable for RAN paging. The paging time window lengths for WB-S1 mode are 1.28 seconds, 2.56 seconds, ..., 20.48 seconds. The paging time window lengths for NB-S1 mode are 2.56 seconds, ..., 40.96 seconds. PTW is UE-specific and is determined by the paging hyperframe (PH), the starting position (PTW_start) and the ending position (PTW_end) within the PH. The PH is selected from one of the CN eDRX superframes based on the UE's identity (UE_ID), e.g. if CN eDRX = 20.56s, there will be 2 superframes (20.56/10.24). The PH is further divided into 4 parts, each equal to 256 SFNs. PTW_start is the starting SFN of one of the parts. The part is selected based on the UE_ID.

eDRX has the same function as DRX, both of which save battery consumption by allowing the terminal device to enter a sleep state periodically at certain times. In the IoT system, the low rate and low frequency of services require the terminal device to have extremely low power consumption. In order to further reduce the energy consumption of the terminal device and meet the extremely low power consumption requirements of IoT devices, eDRX is introduced to cope with its business characteristics. eDRX is an enhancement of DRX, supporting longer sleep time, and significantly reducing the power consumption of the terminal device. In each eDRX cycle, there are several DRX cycles, and several DRX cycles form a paging time window (PTW). The value of the paging time window determines the size of the window and the number of paging. The terminal device monitors the paging channel according to the DRX cycle (the DRX cycle time is short, so it can be considered that the terminal is not dormant and is always reachable) in the PTW. The terminal device is in a dormant state for the rest of the time in the eDRX cycle and does not receive downlink data.

In order to better understand an information acquisition method and device disclosed in an embodiment of the present disclosure, the communication system to which the embodiment of the present disclosure is applicable is first described below.

It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. A person skilled in the art can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

In addition, in order to facilitate understanding of the embodiments of the present disclosure, the following points are explained.

First, in the embodiments of the present disclosure, "used to indicate" may include being used to indicate directly or indirectly. When describing that a certain information is used to indicate A, it may include that the information carries A, or it may also include that the information directly indicates A or indirectly indicates A, but it does not mean that the information must carry A.

The information indicated by the information is called the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, directly indicating the information to be indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, wherein there is an association between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can also be achieved by means of the arrangement order of each information agreed in advance (such as specified by the protocol), thereby reducing the indication overhead to a certain extent.

The information to be indicated can be sent as a whole or divided into multiple sub-information and sent separately, and the sending period and/or sending time of these sub-information can be the same or different. The specific sending method is not limited in this disclosure. Among them, the sending period and/or sending time of these sub-information can be predefined, for example, predefined according to a protocol.

Second, in the embodiments shown below, the first, second, and various digital numbers (such as first indication information, second indication information) are only used for the convenience of description and are not used to limit the scope of the embodiments of the present disclosure. For example, the first and second can be used as type distinctions in the embodiments of the present disclosure, but not as object content distinctions.

Third, the “protocol” involved in the embodiments of the present disclosure may refer to a standard protocol in the communication field, for example, it may include an LTE protocol, a NR protocol, a WLAN protocol, and related protocols in other communication systems, which is not limited in the present disclosure.

Fourth, "at least one" means one or more, and "more than one" means two or more. "And/or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and/or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character "/" generally indicates that the associated objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b and c can mean: a, or b, or c, or a and b, or a and c, or b and c, or a, b and c. Where a, b and c can be single or multiple, respectively.

Fifth, the embodiments of the present disclosure list multiple implementation methods to clearly illustrate the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art can understand that the multiple embodiments provided by the embodiments of the present disclosure can be executed separately, or can be executed together with the methods of other embodiments of the embodiments of the present disclosure, or can be executed together with some methods in other related technologies separately or in combination; the embodiments of the present disclosure do not limit this.

In the related art, as shown in FIG5 , when the core network device configures the eDRX parameters for the terminal device, it only configures the eDRX cycle and the length of the PTW, but does not configure the starting position of the PTW. The starting position of the PTW is calculated based on the identification (ID) of the terminal device. The starting position of the PTW calculated by the terminal device may be located at any position within the eDRX cycle, but in the non-continuous coverage scenario, it is difficult to ensure that the PTW of the eDRX falls within the coverage time period, which is an urgent problem to be solved.

Based on this, the embodiment of the present disclosure provides an information acquisition method, where a terminal device receives first indication information sent by a core network device, wherein the first indication information is used to indicate an eDRX parameter, and the eDRX parameter includes the starting position information of the PTW. Thus, the core network device can indicate the starting position information of the PTW to the terminal device, and can control the PTW to fall in a covered time period, thereby ensuring the reliability of communication.

The following is a detailed introduction of an information acquisition method and device provided by the present disclosure in conjunction with the accompanying drawings.

Please refer to Figure 6, which is a flow chart of an information acquisition method provided by an embodiment of the present disclosure. As shown in Figure 6, the method is executed by a terminal device, and the method may include but is not limited to the following steps:

S61: Receive first indication information sent by a core network device.

In some embodiments, the core network device may send first indication information to the terminal device, and correspondingly, the terminal receives the first indication information.

In some embodiments, the first indication information is used to indicate an eDRX parameter, that is, the first indication information can be used to characterize relevant information of the eDRX parameter, wherein the eDRX parameter includes the starting position information of the PTW.

In the disclosed embodiment, the terminal device may receive first indication information sent by the core network device, the first indication information is used to indicate the eDRX parameters, and the eDRX parameters include the starting position information of the PTW. Thus, the terminal device may determine the starting position information of the PTW based on the first indication information of the core network device, and accordingly, the core network device may send the first indication information to the terminal device, indicating the starting position information of the PTW.

In some embodiments, the core network device sends the first indication information to the terminal device, and may send an attach accept message to the terminal device, the attach accept message including the first indication information. Accordingly, the terminal device may receive the attach accept message sent by the core network device to receive the first indication information sent by the core network.

In some embodiments, the core network device sends the first indication information to the terminal device, and may send a tracking area update accept message to the terminal device, the Tracking area update accept message including the first indication information. Accordingly, the terminal device may receive the tracking area update accept message sent by the core network device to receive the first indication information sent by the core network.

In some embodiments, a mobility management entity (MME) of a core network device may send first indication information to a terminal device, and correspondingly, the terminal device may receive the first indication information sent by the MME of the core network device.

In some embodiments, an access and mobility management function (AMF) of a core network device may send a first indication message to a terminal device, and correspondingly, the terminal device may receive the first indication message sent by the AMF of the core network device.

In some embodiments, the starting position information of the PTW includes paging superframe PH indication information, wherein the PH indication information is used to indicate the PH corresponding to the starting position of the PTW.

In the embodiment of the present disclosure, the starting position information of the PTW includes PH indication information, and the PH indication information is used to indicate the PH corresponding to the starting position of the PTW.

For example, in an eDRX cycle, PHs are numbered in sequence, such as 0, 1, 2, 3, ..., 1023, and the length of a PH is the length of a Hyper SFN, that is, 10.24 seconds. The PH indication information can be used to indicate the PH numbered 3 corresponding to the starting position of the PTW.

Exemplarily, the starting Hyper SFN of an eDRX cycle is Hyper SFN Mod eDRX cycle = 0. The length unit of the eDRX cycle is one Hyper SFN, and mod is a modulo operator.

Among them, Hyper SFN Mod eDRX cycle is the remainder of the Hyper SFN/eDRX cycle.

In some embodiments, the starting position information of the PTW also includes the starting position within the PH.

In the embodiment of the present disclosure, the starting position information of the PTW includes PH indication information, and the PH indication information is used to indicate the PH corresponding to the starting position of the PTW, and the starting position information of the PTW also includes the starting position within the PH. Therefore, the terminal device can determine the starting position of the PTW within the PH included in the starting position information of the PTW based on the starting position information of the PTW, and can determine the specific position in which PH the starting position of the PTW is located.

In some embodiments, the starting position within the PH is a system frame number SFN within the PH, or the starting position within the PH is a specific part among multiple parts included in the PH.

In the disclosed embodiment, the starting position information of the PTW includes PH indication information, and the PH indication information is used to indicate the PH corresponding to the starting position of the PTW, and the starting position information of the PTW also includes the starting position within the PH, and the starting position within the PH is the system frame number SFN within the PH. Therefore, the terminal device can determine, based on the starting position information of the PTW, that the starting position of the PTW is in the SFN within the PH included in the starting position information of the PTW, and determine in which PH the SFN of the PTW is specifically located.

In the disclosed embodiment, the starting position information of the PTW includes PH indication information, and the PH indication information is used to indicate the PH corresponding to the starting position of the PTW, and the starting position information of the PTW also includes the starting position within the PH, and the starting position within the PH is a specific part among the multiple parts included in the PH. Thus, the terminal device can determine, based on the starting position information of the PTW, a specific part among the multiple parts included in the PH included in the starting position information of the PTW, and determine in which specific part of the multiple parts of the PH the starting position of the PTW is located.

Exemplarily, the terminal device can determine the PH corresponding to the starting position of the PTW based on the starting position information of the PTW, wherein, if the PH includes N parts, and N is 4, if the starting position information of the PTW also includes the starting position within the PH, the starting position within the PH is a specific part among the multiple parts included in the PH, and when the specific part is the second part, the starting position of the PTW can be determined to be the starting position of the second part.

In some embodiments, the PH indication information includes a starting PH position and an ending PH position, or includes a starting PH position and a length, or includes only a starting PH position.

In the embodiment of the present disclosure, the starting position information of the PTW includes PH indication information, and the PH indication information is used to indicate the PH corresponding to the starting position of the PTW. The PH indication information also includes a starting PH position and an ending PH position. Thus, the terminal device can determine one or more PHs corresponding to the starting position of the PTW, as well as the starting PH position and the ending PH position corresponding to the one or more PHs.

In the embodiment of the present disclosure, the starting position information of the PTW includes PH indication information, and the PH indication information is used to indicate the PH corresponding to the starting position of the PTW. The PH indication information also includes the starting PH position and length. Thus, the terminal device can determine one or more PHs corresponding to the starting position of the PTW, as well as the starting PH position and length corresponding to the one or more PHs.

In the embodiment of the present disclosure, the starting position information of the PTW includes PH indication information, and the PH indication information is used to indicate the PH corresponding to the starting position of the PTW. The PH indication information also includes the starting PH position. Thus, the terminal device can determine one or more PHs corresponding to the starting position of the PTW, and the starting PH position corresponding to the one or more PHs.

In some embodiments, the terminal device may determine the length based on the protocol agreement, thereby the terminal device may determine one or more PHs corresponding to the starting position of the PTW, and the starting PH position and length corresponding to the one or more PHs.

In this implementation mode or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, and the optional methods or optional examples can be arbitrarily combined and can be arbitrarily combined with other implementation modes or examples.

By implementing the embodiment of the present disclosure, the terminal device receives the first indication information sent by the core network device, wherein the first indication information is used to indicate the eDRX parameter, and the eDRX parameter includes the starting position information of the PTW. Thus, the terminal device can receive the starting position information of the PTW indicated by the core network device, and can control the PTW to fall in the covered time period, thereby ensuring the reliability of communication.
